Has anyone ordered a snack pack from Amazon to take with them on the trip? DD loves various snacks, and I think this would keep her happy instead of shelling out lots of money on vacation at airports, parks, etc. In the past I have used Garden Grocer, but now we are staying at Swan and I don't want to deal with having to meet a delivery kind of thing, and am just bringing snacks in our suitcase. Thanks for any suggestions!
